North Korea informed the International Atomic Energy Agency (IAEA) on Tuesday that it would stop all cooperation with the UN nuclear watchdog immediately, IAEA spokesman Marc Vidricaire said.

IAEA inspectors are present in North Korea to monitor that the country's nuclear installations remain dismantled and turned off.

North Korea has informed the IAEA that it plans to reactivate all nuclear facilities, which include a reactor and a plant to reprocess spent nuclear fuel.

The country said earlier on Tuesday that it would boycott international negotiations on ending its nuclear weapons programme and restore nuclear facilities in reaction to the UN Security Council's condemnation of a North Korean rocket launch.
